Abstract

A study was conducted on the effect of oven drying temperature on tannin content of bungur leaves (Lagerstroemia speciosa Auct. non (L.) Pers). Bungur leaves were picked, dry sorted, washed, wet sorted, and drained then oven dried at 30oC, 60(o)C, 90oC respectively. After drying, the samples were then measured for moisture content and then made into bungur leaf powder. Bungur leaf powder was then extracted by modified maceration using aquadem solvent. The extract obtained was tested qualitatively and quantitatively. Qualitative test results showed the presence of tannins. Quantitative tests using permanganometry, obtained tannin levels at drying temperatures of 30oC, 60oC, and 90oC were 7.27% ± 0.1429, 15.26% ± 1.0610, and 9.92% ± 0.7156, respectively. The highest tannin content was obtained at 60oC drying temperature.

Abstract

Mekanisme kerja bahan pemutih salah satunya adalah menghambat aktivitas enzim tyrosinase. Ekstrak metanol rimpang Lakka-Lakka (Curculigo orchioides Gaertn.) telah diteliti dapat menghambat aktivitas enzim tyrosinase dengan nilai IC50 10,2 bpj. Oleh karena itu dapat diformulasi menjadi krim pemutih yang stabil secara fisika kimia dan aman untuk digunakan. Penelitian ini bertujuan untuk mendapatkan formulasi krim pemutih tipe a/m dari ekstrak metanol rimpang Lakka-Lakka (Curculigo orchioides Gaertn.) yang stabil secara fisik dengan emulgator Polisorbat 60-Sorbitan 60.Pada penelitian ini rimpang Lakka-Lakka dimaserasi dengan menggunakan penyari metanol kemudian diuapkan hingga diperoleh ekstrak kental, kemudian dibuat sediaan krim pemutih tipe a/m dengan menggunakan emulgator Polisorbat 60–Sorbitan 60 dengan konsentrasi 1%, 2% dan 4%. Pengujian kestabilan fisik krim meliputi pengukuran viskositas, tetesan terdispersi, pengukuran pH, dan inversi fase sebelum dan setelah kondisi penyimpanan dipercepat selama 12 jam secara bergantian pada suhu 5oC dan 35oC sebanyak 10 siklus.Pengujian kestabilan fisik memperlihatkan krim yang menggunakan emulgator Polisorbat 60-Sorbitan 60 pada konsentrasi 1%, 2% dan 4 % stabil secara fisik karena viskositas, tetes terdispersi, pH tidak mengalami perubahan yang signifikan dan krim tidak mengalami inversi fase sebelum dan setelah penyimpanan dipercepat. Formula krim yang paling stabil yaitu krim dengan emulgator Polisorbat 60-Sorbitan 60 konsentrasi 4% karena berdasarkan hasil uji viskositas krim ini paling kental, dimana semakin kental suatu krim maka semakin mampu mencegah terjadinya penggabungan tetesan terdispersi dan sedimentasi atau kriming yang menghasilkan terjadi pemisahan fase.

Abstract

Purpose: This community service program is designed to increase the quantity and quality of pure coconut oil production. through a partnership with Mitra Mina Malole. Methodology/approach: A participatory approach is implemented through training on VCO fermentation technology, mentoring on the use of appropriate tools, and regular implementation evaluations. The implementation team, comprising lecturers and students, collaborates directly with the partner community to transfer technology and monitor production outcomes. Results/findings: The community service program demonstrated an increase in production capacity, from 10–13 bottles per day to 20–25 bottles in 100 mL packaging, as well as improved product quality, resulting in a more hygienic and high-quality product. The product has obtained a P-IRT label and permit, and marketing has begun to expand, contributing to increased income and welfare for the local community. Conclutions: Community partnerships through appropriate technology and training have successfully improved the quality and production capacity of Virgin Coconut Oil in Ingguinak Village, increased family income, strengthened local business institutions, and expanded market access with more competitive and hygienic products. Limitations: The limited time for implementation means that ongoing support is still very much needed. Limited access to logistics and infrastructure in remote areas means that product distribution is not yet optimal. Contribution: This Program provides tangible socio-economic impacts for coconut farming communities. This program's recommendations can serve as a reference for developing broader community service policies and practices, supporting sustainable development, and strengthening local natural resource-based community economies.
